Forward-looking fishability derived from forecast air temp, wind, precipitation, and pressure trend. Trout-tuned: prime water-temp band 50–65°F, stress >68°F. Spate UP rivers respond to rain in hours-to-a-day; clarity recovers within 24–48h after <1″ events. Confidence: Day 1–2 good, Day 3 moderate, Day 4–5 indicative only.

Hatch Chart — Western UP monthly highlights · current month highlighted

Month	Key Hatches & Fly Patterns

Western UP is a Lake Superior watershed — hatches run later than southern Michigan. July Hexagenia (the “hex”) is the headline event for big browns; brook trout fish well on terrestrials July–September. Fall salmon & steelhead arrive Black River first, then mid-shore tribs.

Fishability Summary (0–100)

PRIME 75–100 Get on the water

GOOD 60–74 Worth the drive

FAIR 45–59 Workable — pick your window

MARGINAL 30–44 Tough bite likely

TOUGH < 30 Tie flies / scout access

Wind Speed (5–6 wt rod)

0–8 mph Negligible · easy casting

8–12 mph Minor · still comfortable

12–18 mph Moderate · shorten casts, heavier flies

18–22 mph Significant · accuracy & distance suffer

22+ mph Adverse / unsafe · stand down

Pressure Trend (3-hr Δ, inHg)

RAPID FALL ≤ −0.10 · feeding now, fish before storm

FALLING −0.10 to −0.03 · pre-front feeding window

STABLE −0.03 to +0.03 · reliable baseline activity

RISING +0.03 to +0.10 · steady feeding

RAPID RISE ≥ +0.10 · post-front · bite often stalls

Water Temperature (trout)

< 45°F Cold · slow presentations, midges/streamers

50–65°F Ideal feeding window · prime hatches

65–68°F Marginal · fish early/late

> 68°F Stressful · consider standing down (esp. brook trout)

Flow brackets — per stream Western UP rivers vary from intimate spring creeks to big freestone systems · thresholds calibrated per gauge (score Δ in parens)

Very low Spooky fish, tiny tippet (−10)

Low-normal Good wading visibility (0)

Prime Ideal wading & drifts (+5)

Elevated Streamers & banks · stained (−5)

High / blown Off-color, unsafe wading (−20)

Western UP Note

These are cold-water freestone rivers — flows respond fast to rain (<24h), and clarity returns about as quickly. Brook trout are the wild gem; brown trout dominate stocked & self-sustaining sections. Watch the Hex in late June–July, and time fall trips to Black River salmon/steelhead (Sept–Nov). Always confirm current Michigan DNR regulations before fishing — the West Branch Ontonagon spring closure is enforced and Type designations vary by river segment.

About the data: Stream flow, gauge height, and (where reported) water temperature come live from the USGS Water Services API and NOAA NWPS API. Air temperature, wind, humidity, and barometric pressure come from Open-Meteo, centered on whichever river is selected above. Pressure trend is the 3-hour hPa delta converted to inHg.

Per-river flow brackets: the Black River fishes prime around 80–250 cfs while the Middle Branch Ontonagon below Bond Falls handles 600–2,500 cfs — each river has its own calibrated thresholds (see Condition Guidance). Water temperature is only reported by USGS at the Presque Isle near Connorville gauge — for other rivers the dashboard estimates a workable read using air temp as a proxy. The South Branch at Ewen (EWNM4) and East Branch (Sparrow Rapids/Kenton) USGS sites are intermittently telemetered; the dashboard falls back to NWPS or a regional proxy gauge (PAUM4 / RKLM4) when their feeds are stale.

Critical regulations: The West Branch Ontonagon from the Victoria Hydro Station tailrace upstream to Victoria Dam (including the tailrace canal) is CLOSED to all fishing April 1 – June 10 annually for spring spawning protection. The East Branch Ontonagon north of M-28 is a Type 3 stream and is open year-round. The Black River in Gogebic Co. is a Type 2 stream with a year-round season. Always verify current rules in the Michigan DNR Fishing Guide before heading out.
